containing fillings or products for infants and young children aged 36 months
or below (see Chapter 1; see Chapter 1 of the 2012 edition);
-- The assessment indicators such as dimensional change rate after dry cleaning,
color fastness to dry cleaning, and appearance quality after washing are added,
and the content that shirts worn by children aged older than 36 months and no
older than 14 years shall also comply with the relevant provisions of GB 31701
is added (see 4.2; see 4.2 of the 2012 edition);

4.2.1 of the 2012 edition);
-- The specification deviation and measurement regulations on the clothes length
are modified, the specification deviation requirements for the neckline of
superior products are modified, and the specification tolerance of the length of
short sleeves is added (see Table 3 and Table 6; see Table 3 and Table 4 of the
2012 edition);
-- The intrinsic quality inspection conditions are modified (see 5.4; see 5.3 of the
2012 edition);
-- The test method for the distortion rate after washing is modified (see 5.5.7; see
5.4.7 of the 2012 edition);
-- The test method for color fastness to dry cleaning is added (see 5.5.14);
-- The test method for color fastness to transfer in joints is modified, and the
original Appendix A is deleted (see 5.5.17; see 5.4.16 and Appendix A of the
2012 edition);
-- The test method for appearance quality after washing is added (see 5.5.18);

garments, the calculation of clothes length is based on the average value of the
measured lengths at four positions on the left and right sides of the front and the back;
for raglan-sleeved garments, the clothes length is measured only from the midpoint of
the back neck to the hem. Mark the measurement to facilitate measurement after
washing.
5.5.6.2 Washing and drying test

humidity of (65±4)% and conditioned for no less than 4 hours, and the creases are gently
patted flat before measurement. The number of test pieces is 3.If there are both
shrinkage and elongation test results, the average value of the two shrinkage (or
elongation) specimens is taken as the test result.

It shall be implemented in accordance with the provisions of Method A in GB/T 31127-
2014.
5.5.18 Test for appearance quality after washing
Washing and drying shall be implemented according to the test method for dimensional
change rare after washing specified in this standard, and then the evaluation is carried
out according to Table 1; the crinkle degree of the collar, sleeve, top fly and side seam
after washing is rated according to GSB 16-3605; the color change after washing is

6 Judgment rules
6.1 Batch determination
6.1.1 Intrinsic quality
If any one of the internal quality items does not meet the requirements, the batch of
products will be deemed unqualified. Among them, if the color fastness item does not
meet the requirements, the batch of products will be deemed unqualified by color. For
the test for appearance quality after washing, if at least two or more pieces meet the
requirements, the batch of products will be deemed qualified, and if not, the batch of
products will be deemed unqualified.
6.1.2 Appearance quality
For the appearance quality, the non-conforming product rate is calculated by the type
and color. If the non-conforming product rate is within 5.0%, the batch of products is
considered qualified; if the non-conforming product rate exceeds 5.0%, the batch of
products is considered unqualified.
6.1.3 Result determination
If the products are qualified according to 6.1.1 and 6.1.2, then the batch of products is
qualified.
